Ostaci pesticida u poljoprivrednom zemljištu Vojvodine
Pesticide residue in agricultural soil in Vojvodina province
Projekat: Unapređenje remedijacionih tehnologija i razvoj metoda za procenu rizika zagađenih lokaliteta (MPNTR - 43005)
Sažetak
Nagomilavanje pesticida u zemljištu predstavlja ozbiljan ekološki problem, posebno imajući u vidu mogućnost transporta do ostalih članova ekosistema, površinskih i podzemnih voda, te pojavu fitotoksičnosti kod narednih useva u plodoredu. Monitoringom sprovedenim u okviru ovog istraživanja, provereno je prisustvo ostataka fungicida i isekticida u poljoprivrednom zemljištu na području Srema. Analizirano je prisustvo ostataka 29 pesticidnih aktivnih supstanci u 56 uzoraka zemljišta, a analiza je izvedena gasnom hromatografijom sa masenom spektrometrijom. Ukupno posmatrano, najčešće detektovani su bili ostaci flusilazola, pirimetanila, propikonazola i piriproksifena. U Republici Srbiji, od pravilnika vezanih za maksimalno dozvoljene količine ostataka pesticida u zemljištu, na snazi je Uredba o programu sistematskog praćenja kvaliteta zemljišta, indikatorima za ocenu rizika od degradacije zemljišta i metodologiji za izradu remedijacionih programa (Sl. glasnik RS, br. 88/2010), ali se odnosi na pesticide koji više nisu u prometu.
Abstract
The accumulation of pesticides in the soil presents a serious ecological problem, especially considering the possibility of transport to other members of the ecosystem, surface and groundwater, and the phytotoxicity of the next crop in the rotation. Monitoring carried out within this study, a presence of fungicide and insecticide residues was determined in the region of Srem. Presence of 29 pesticide active substance residues in 56 soil samples was analyzed, and it was carried out by gas chromatography with mass spectrometry. In general, the most commonly detected were the residues of flusilazole, pyrimethanil, propiconazole, and pyriproxyfen. In the Republic of Serbia, regarding the Regulations that refer to the maximum residue level of pesticides in the soil, the Regulation on the Program for Systematic Monitoring of Land Quality, by indicators for assessing the risk of land degradation and the methodology for making of remediation programs (Official Gazette of RS, No. 88/2010) exists, but it refers to the pesticide products that are no longer on the market.
